| /* Suppress use of exceptions here to avoid build errors if the FE_* |
| macros aren't definied. Only allow rounding modes implemented for |
| MicroBlaze. |
| |
| This does mean that some code will silently fail to report exceptions, |
| set rounding mode as expected, etc., but it allows math code to compile |
| that otherwise wouldn't (such as math/s_fma.c) and so is valuable. |
| |
| We intentionally ignore the "exception" arguments of functions that |
| take an exception, since we can't even evaluate the argument |
| without causing a build failure. The extra level of statement |
| expression wrapping avoids "statement with no effect" warnings. |
| Since the callers don't check for errors anyway, we just claim |
| success in every case. |
| |
| The overrides for libc_ functions must happen before we include |
| the generic math_private.h, and the overrides for regular |
| <fenv.h> functions must happen afterwards, to avoid clashing with |
| the declarations of those functions. */ |
